Summary:This study proposes a Fresnel-lens-based radome design with the use of polycarbonate (PC) material to achieve a flat-top beam when integrated with the feeding antenna. By utilizing generalized laws of refraction and reflection, the radome is designed based on the radiation pattern of the feeding antenna and the desired flat-top pattern. One can implement the derived phase shift profile by designing the thickness for each region to achieve the desired pattern. Simulation and measured results of the proposed radome at the frequency of 12 GHz show that the half-power beamwidth (HPBW) of the radome with feeding antenna is improved. This approach is suitable for satellite communication applications requiring a wider field of view.
